Abstract

scid mice naturally infected with Pneumocystis carinii and inoculated with a normally apathogenic pneumovirus had significantly higher P. carinii cyst counts and developed significantly more severe P. carinii-related disease than did sham-inoculated, P. carinii-infected scid mice. P. carinii-free, virus-infected scid mice survived for 2 months despite high pulmonary virus titers. These results show that a respiratory virus infection can exacerbate P. carinii disease in an immunocompromised-rodent model.
